This invention Arelates to improvements in 'winding machinesfand particularly to a locking device of the clamping type for the member carrying the thread guides and the feeler 4which member is moved intermittently on thecops being wound.

It is already known in winding machines to provide la locking device forthe above mentioned member which device takes' part together vwith the carrier member. in the intermittent movements o fk the latter in fone direction and which locks that `member inits momentary position and prevents .it` from carrying out an undesiredmovement in the opposite'direction According to my invention the locking devicer is provided .with

a clampingsleevehmounted on the guideA rod off said memberv and which locking device is adapted to lock the carrier member by means of an abutment. member cooperating with a tapering surface.

A locking device of this type 'presents the advantage as compa-red with the known devices of a greater simplicity andof being influenced to a. much smaller degree by dirt and oil. The abutment member may be formed by an adjustable pin enabling an adjustment of the tension of a spring coacting with the clamping sleeve and thereby varying the clamping action of the sleeve.

ln a preferred construction the,V abutmentv member may consist of al roller whereby the terially increased.

Referring to thel first; constructional eX- ample illustratedl in Figs.1-S.1,denotes the.l guide rod for. the carrier member-2, which ismounted on the` rod 1 with little radial clearance.

Thesleeve- 4 is provided at its outer surface with a tapering face 4', in the exemplification shown the tapering facing 4 extends over its whole. circumference andI forming ythus aconical-surface, which-is pressed by the action of a compression spring vagainst the `rounded'head of-aset screwv 6. The

latter .actav las the. abutment `member Yand is adapted to be adjusted in' the sleeve 3.

The cop spindle 9 which is parallel to j `the guide rod 1 performs during the opera- -tion of the winding machine a` reciprocating and simultaneously a turning motion, the gear for imparting such motions 1s arranged inside the casing 12 and may be of a similar y 191,1, erin ,mylar-Swiss Letters Patent No.
